INFLUENCE OF THREE-DIMENSIONAL PERTURBATIONS ON HEAT TRANSFER IN HYPERSONIC FLOW
ABSTRAKT
The present paper deals with the three-dimensional flow in a shock layer at supersonic transverse flow conditions over the front surface of a cylinder and a sphere under small, spatially periodic perturbations along the transverse coordinate. Based on the numerical solution of the unsteady three-dimensional Navier−Stokes equations, it is shown that small imposed perturbations of the free-stream velocity (0.5−3 %) along the transverse coordinate lead to the shock curvature and cause the formation of vortex structures in the shock layer and significant perturbations of the heat flux on the surface.
